Specification forming part of Letters-Patent No. 36.789, dated October 28, 1862.

To @ZZ whom, t may concern,.-

Be it known that we, JoI-rNILA'rr, of Oldham, in thecounty of Lancaster, England, me-

gin known as McCarthys, and in which onev roller is employedin conjunction with axed i and vibrating blade; and it consists, first, in

the employment of two of such vibrating blades acting alternately upon the usual roller and fixed blade; and, secondly, in the adaptation of apparatus whereby the material is regularly' supplied to the roller and blades, and is presented thereto in a more open andsuitable condition for the separation of the seeds.

In the accompanying drawings, Figurel represents the operative parts of our improved gin in section, and F ig. 2 is a face view of the vibratingblades and the apparatus by which they are caused to operate.

The usual roller is at a, and its xed blade at b. Beneath these is what may be called the usual vibrating blade, c, mounted upon 1evers d, which turn upon a center at e, and at f are the cranks bywhich the vibrating m0- tion is communica-ted. In Fig. l the connecting-rodl g of the cranks is broken off, itbeing too long to vbe shown in the drawings; but at Fig. 2 the arrangement isishown entire. 'At 7L is the second vibrating blade, which constitutes this part of our-invention, mounted upon levers y, turning upon a center at z, and which is connected toanother pair of cranks by connecting-rods at, and the two are so arranged that when one is ascending the other is descending, so that these two blades c h act alternately, thus affording two operators upon the material for one revolution of the crankshaft. Thus far we have described the first part of our invention as it may be applied by itself toV the aforesaid descriptionof gin, and we now proceed to explain another part of our'invention, which may be combined therewith or may be usedl in conjunction with the ordinary oneblade machine. The frame-work is extended at lc and carries a feed-apron, Z, which is caused to travel so as to convey the material toward y the operating part of the machine. At m is a iiuted roller, between which and the feed-apron the material is retarded. At a is a roller furnished with spikes, which, by being caused to revolve in the direct-ion of the arrow, opens or combs out the bers. Upon the roller a is a crank-pin, o, connected to a block, p, to which .are adapted two rods, q, encircled by springs r. rlhese springs abut against a second block, s, through which the rods q pass, and in which they are capable of sliding. The block s is connected by a center-pin to a lever, t, fixed upon a shaft, u, by which arrangement therefore the said shaft u is caused to vibrate in its bearings, and this is done through the medium of the springs 1', and if, therefore, any undue resistance should be offered these springs will give way and allow the rods g to slide in the block s. To the shaft a is attached a series of combs, o, extending across the machine, which combs, in vibrating with the shaft u, pass through a series of'stationary combs, lw, from thence through the teeth of the spiked roller a, from which theydraw off tufts of the cotton, and a further downward motion of the combs c will present the said tufts to the action of the vibrating blades h c, after which the Vcombs c will return to the position shown in the drawings, ready to operate as before. At w is a fluted roller, which is caused to revolve nearly in contact with the roller ,so as to keepv its surface clear of the material. The several parts may be caused to revolvein the direction of the arrows by any ordinary arrangement of gearing, .but the redy circles indicatefthe pitch-lines of vwheels which may be employed for that purpose.

Ve have in the foregoingdescription alluded to a particular arrangement and combination of machinery; but we do not conne ourselves thereto, asv manymodifications may be adopted without departing from the spirit of our h invention. For instance, in that part thereof relating to the opening out or combing of the material the spiked roller and transferringcomb need not of necessity be used together, for the latter might draw the material from fixed points or bars in detached tufts, so as to effect a preparatory opening. We would also remark that instead of the spiked roller apparatus similar' to gills or other opening` arrangements may be employed.

l The following is what We claim as new in .the above-described invention, and desire to secure by Letters Patent:

l. The two alternately-reciprocating blades c h, constructed and arranged to operate in combination with each other and with the roll er a and breast b of the McCarthy cotton-gin in the manner and for the purposes herein shown and explained.

2. The employment or use of combing or carding instruments, substantially as herein described, for opening the material preparaaavse c tory to its presentation to the ginning` mechanism a b c. y

3. The transferring-comb u c, constructed as described, and employed to present thematerial in tufts to the ,grinning` mechanism a b c, substantially as and for the purposes set forth. 4. The elastic or yielding,` connecting-rod 0 p q, employed to operate the comb u o, substantially in the manner described. JNO. PLATT. VILLIAM RICHARDSON, Witnesses: y
